IMPROVEMENT IN STANDARDS FOR CARRIAGE-TOPS.

Specification forming part of Letters Patent No. 209,097, dated October15, 1878; application filed September 2, 1878.

To all whom it may concern Be it known that I, FRANCIS W. WHITNEY, ofLeominster, county of Worcester, State of Massachusetts, have inventedan Improvement in Standards for Carriage-Tops, of which the followingdescription, in connection with the drawing forming a part thereof, is aspecification.

This irwention relates to an improved standard for the tops of childrensor other carriages, to enable the same to be adjusted and held inadjusted position above, back, or in front of the seat, as may bedesired.

The invention consists chiefly in the construction of the friction-jointintermediate between the two parts of the standard, it being composed oftwo disks, preferably of wood or equivalent material, which are embracedby an annulus or ring, the two disks being forced upon the annulus by abolt and nut or equivalent clamping devices.

Figure 1 represents, in elevation, the outer side of a standardconstructed in accordance with this invention; Fig. 2, a verticalsection of Fig. 1; and Fig. 3, a detail of the inner loose cap or plateof the clamp.

This standard is composed of two parts, a b, of cast metal, the formerbeing attached to the top and the latter to the seat of the carriage, inany usual way.

At the upper end of the portion 1) is a capshaped or circular flangedportion, 0, within which is laced one of the wooden or other disks thesaid disk being provided, as shown in the drawing, with openings, toreceive pins 0, projecting from the portion 0, said pins preventing therotation of the disk.

The lower end of the portion a is provided with a loop, f, within whichis placed the ends 2 2 of a ring or loop, g, of wire, the said loopbeing soldered or otherwise securely held in place at the lower end ofthe portion a, and being fitted to the concaved periphery of the disk(I. When this loop gis placed about this disk d, as shown in Fig. 2, thesecond disk, It, is placed next the disk cl at the opposite side of theloop. The cap-like portion i (see Fig. 3) is then placed outside thedisk It, as in Fig. 2, the pins 3 011 i entering holes in disk h toprevent its rotation, and the opening 4 in ear j,

attached to i, fitting over the pink, projeetin g from b, to therebyhold 1' in the proper position with relation to c.

The bolt 1 is extended through the parts c'h cl 0, and a thumb-nut, m,is screwed upon the said bolt, so that when the said thumb-nut is turnedupon the said bolt toward its head the concave portions of said disks orfriction de vices h d are caused to bear with more or less force uponthe interior of the loop g, and hold the same in adjusted position.

The degree of pressure of these frictiondisks may be varied at will, soas to cause more or less force to be exerted to turn the portion a andits attached top with reference to the portion 1) and the seat of thecarriage.

The disks h (I may be of hard rubber, paper board, or other materialwhich preferably will not require oil between them and the annulus 9.Each disk may be of one or more pieces.

It is obvious, instead of attaching the annulus g to the portion a ofthe standard, that it may be attached to the portion b, and that thedisks and the portions 0 i may be connected so as to move with a withoutdeparting from my invention but theform shown in the drawin g ispreferable.

I claim- 1. In a carriage-standard, the combination, with one portion ofthe standard provided with a connected wire ring or annulus, g, of twoindependent grooved clamping-disks and mechanism to force them togetherto embrace and hold the said annulus and its connected portion of thestandard in position by friction between the parts, substantially as described.

2. The portion b of the standard provided with the cap-like part c, theindependent caplike portion 17, the disks h d, the portion a of thestandard, and the annulus 9, combined with a clamping device to forcethe disks against the annulus, substantially as described.

3. The cap-like portions 0 and i of the standard provided 'with pins orprojections, combined with the disks provided with openings to receivethe said pins to hold the disks in position, substantially as described.

4. The combination, with the portion i and the standard, of a pin orprojection on one to In testimony whereof Ihave signed mynamc enter aslot or recess in the other to retain the to this specification in thepresence of two subportiont'in position, substantially as described.scribing witnesses.
